Product Overview | Shutoff Valves
In abnormally hot, dirty, or corrosive conditions, most shutoff valves can deteriorate and fail to shut off tightly. Frequent, periodic checking of all valves is recommended. Threaded ball valves are designed for industrial, residential and commercial use on steam, water, oil or gas. Their full ports allow for maximum flow with minimum pressure drop and turbulence. The valve is UL listed, FM approved, and the brass bodies are CGA 3.16 certified.
1821B ball valves can be ordered with the option to be cleaned for oxygen service. A locking handle option is also available.
